STATEN ISLAND, N.Y. -- A Castleton Corners teen who apparently leaped from the top of a six-story apartment building Sunday night has died of his injuries, police confirmed yesterday.

A childhood friend described Divine Fernandez, 18, as a kind, quiet soul who had recently taken to posting sad and morbid updates to his Facebook and Instagram profiles.

About 9:20 p.m. Sunday, police confirmed, Fernandez, who lived at 20 Laguardia Pl., in the Todt Hill Houses, apparently jumped off the roof of 204 Schmidts Lane, another building in that same complex.

He was rushed to Richmond University Medical Center, West Brighton, where he was later pronounced dead.

"He was a sweet and loving kid," said Kaitlin Benardello, 21, who lives in the apartment complex and said she had known Fernandez for the last nine years. "He's very quiet. He wasn't like all the other kids on Staten Island."

Fernandez had written about being sad and lonely, including a March 11 Facebook post stating, "Nobody likes me," and had talked about recent romantic troubles, she said.

And, she said, a recent Instagram post, viewable only by his followers, read, "We live alone. We die alone. And life is an illusion."

Fernandez loved basketball, she said, and could often be found outside shooting hoops.

Advance records show Fernandez swam competitively for Susan Wagner High School in 2008.

Fernandez's family members declined comment Monday, saying that they weren't ready to talk about him or what happened.

The incident happened roughly an hour and a half after a female motorist abandoned her vehicle on the Verrazano-Narrows Bridge and appeared to have jumped off. No body has been recovered, police said, and no information was available about her identity.
